Objective: This study aimed to investigate the influence of child care center managers’coaching leadership on teachers’motivational self-concepts via middle managers’coaching leadership. Teachers’motivational self-concepts consisted of personal self-concept and social self-concept. Methods: A questionnaire survey was conducted on 475 child care center teachers regarding teachers’recognition of the coaching leadership of managers and middle managers and motivational self-concepts of teachers. To analyze the collected data, the path was examined through descriptive statistics, correlation analysis, structural analysis using Amos, and the mediating effect was confirmed by conducting the Sobel Test. Results: The middle manager’s coaching leadership was found to mediate the pathways from the manager’s coaching leadership to the teacher’s social self-concept, but did not mediate the personal self-concept of teachers. Conclusion/Implications: This study showed that the manager’s coaching leadership was mediated by the middle manager’s coaching leadership and that the manager’s coaching leadership had an influence on the social self-concept of teachers. These results imply that both managers and middle managers need to develop coaching leadership skills in order to improve the motivational self-concept of teachers, which is important for work efficiency at child care centers.
